Polypropylene Mooring Lines (Our Product) | Mooring in calm waters, recreational boating | Buoyant (specific gravity 0.9), UV resistance (ASTM D4355, 500h▲), breaking strength: 5 kN (Industry) ▲ 6 kN (Base) ▲ 7 kN (Advanced) | ▲▲▲ Lightweight & cost-effective, floats in water, UV-resistant (500h▲) | Lower strength than synthetics, less abrasion resistance vs polyester |
Nylon Mooring Lines | Heavy-duty towing, commercial ships | High elasticity (20% elongation), breaking strength 8 kN, sinks (specific gravity 1.1), UV resistance (ASTM D4355, 300h) | Shock absorption, high strength (8kN), durable | Sinks, less UV-resistant, heavier than polypropylene |
Polyester Mooring Lines | Long-term mooring, UV-exposed areas | UV resistance (ASTM D4355, 1000h▲▲), breaking strength 6 kN, sinks (specific gravity 1.3), abrasion resistance (ASTM D3389, 150 cycles) | ▲▲▲ Superior UV resistance (1000h▲▲), moderate strength, durable | Heavier, sinks, less buoyant than polypropylene |
Kevlar Mooring Lines | High-load applications, military | Extremely high strength (12 kN▲▲▲), lightweight (specific gravity 1.4), cut-resistant (ASTM D3389, 200 cycles▲) | ▲▲▲▲ Highest strength (12kN▲▲▲), lightweight, cut-resistant (200 cycles▲) | Expensive, less elastic, requires careful handling |
Manila Rope | Low-cost setups, traditional uses | Natural fiber, sinks (specific gravity 1.5), moderate strength (3 kN), UV degrades (ASTM D4355, 100h) | Cost-effective, traditional | Low UV resistance (100h), weaker, sinks |
High-Modulus Polyethylene (HMPE) | Extreme loads, high-performance | Ultra-high strength (15 kN▲▲▲▲), floats (specific gravity 0.97), UV resistance (ASTM D4355, 800h▲▲), lightweight | ▲▲▲▲▲ Strongest material (15kN▲▲▲▲), floats, UV-resistant (800h▲▲) | Very expensive, requires special handling, low abrasion resistance (ASTM D3389, 80 cycles) |
